Excessive humidity is just as bad as very dry air. It negatively affects a person’s well-being.

In addition, there are other consequences: the environment deteriorates, things deteriorate, as well as elements of supporting structures.

As a result excess humidity In the room, the parquet swells and the wallpaper warps, the doors swell, the walls become covered with huge spots of mold, after a while things begin to become damp and smell unpleasant.

In addition, furniture with paintings may deteriorate, various musical instruments, parts made of wood are affected by harmful microorganisms. The house is filled with mold microspores and acquires an unpleasant odor.

WITH high humidity in the house you can fight with this classic way, like ventilation, or you can use a modern dehumidifier for the apartment.

Advanced equipment works on the basis of various physical principles that help reduce humidity in the room, as well as constantly maintain the conditions of a particular environment at an appropriate level.

Nowadays there is The four main types of household dehumidifiers for the home are:

• adsorption moisture absorber;
• compression or evaporation;
• a device created based on the Peltier principle;
• rotary adsorption.

The first type operates thanks to the adsorbent, which is contained inside and perfectly absorbs moisture.

Evaporative dryer It works due to the fact that moist air is directed to a cold surface, where it condenses and flows into a special compartment.

Third type is equipment containing a Peltier element. It is based on the cooling effect of several semiconductor structures as a result of the passage of electric current through them.

Rotary adsorption dryer- This is an improved class, the principle of operation of which combines the two previous ones.

Working principle of a condensation dryer

Condensation type dryer It works on the principle of condensation of water vapor contained in the air. The operation of this method is carried out by the functioning of the refrigeration circuit, interacting with the condenser and evaporator, located close to each other. He considered the most effective from an economic point of view.

The air in the room is dehumidified as follows:

• Thanks to the engine, moist air is pumped into the system of the device.
• Then the evaporator cools it with the help of a refrigerant.
• The dehumidified and cooled air is passed through a hot condenser and returned to the room.

Condensation dryers have several advantages:

• mobility,
• autonomy,
• compactness,
• wide range of models.

They are great for:

• household premises, which are characterized by a small cubic capacity,
• water parks,
• rooms with swimming pool.

The efficiency of their work decreases significantly with a sharp drop in temperature environment, and at temperatures below +10°C it is useless to use such devices.

A condensing device reduces the percentage of humidity by 6 - 8%. However, the temperature in the room will drop by more than 3°C.

DIY refrigerator dehumidifier

You can make a condensation dehumidifier for humid air yourself using available materials.

To make the device you will need:

• an old freezer that is in working order;
• a small piece of organic glass with dimensions matching the parameters of the camera;
• products for fastening - self-tapping screws;
• sealant – silicone glue;
• two fans;
• electric heater;
• hollow rubber tube.

First you need to dismantle the door of the selected freezer.

One fan should be securely attached to the bottom of the piece of plexiglass., so that it definitely blows into the freezer. To do this, you need to make a mounting hole of the appropriate size in the organic glass. Self-tapping screws are used for fastening, and each joint is carefully treated with sealant.

Another fan needs to be attached to the top of the glass. It is designed to exhaust hot and dry air back into the room. It is unfolded so that it blows out the air flow.

Then you need to install the hollow rubber pipe . Its role is to remove condensed moisture from the dehumidifier.

For installation, a small hole must be drilled in the bottom of the device. A hose is inserted into it, after which the edges of the hole are treated with silicone glue. A capacious vessel is placed under the tube to allow the condensation to drain there.

At the last stage, organic glass with fans is mounted in freezer instead of the old door.

How to get rid of dampness in an apartment: other methods of drying

Today it is known There are three main ways to dry humid air:

1. Assimilation thing is cold air contains relatively less water vapor than warm. It is considered not very effective for two reasons: moisture may not be absorbed all the time and only in limited quantities, consumption large quantity electrical energy;
2. Adsorption method developed on the sorption properties of special substances called sorbents. The device contains porous material, but the efficiency of the sorbent decreases significantly as it becomes saturated. Its disadvantage is the energy consumption in huge quantities, as well as a short service life. In this case, it is better to use silica gel on a fiberglass carrier;
3. Condensation method based on the condensation of water vapor contained in the air.

Humidity in a room can be measured using several instruments:

• hygrometer,
• wet glass
• thermometer.

Most simple method is the use of a special measuring device - a hygrometer. Today there are several varieties of it. Their action is based on different principles. These devices will help you easily determine what humidity should be in the house.

Adsorption type air dryer is a device that removes excess moisture from the air, which is explained by the properties of adsorbents.

To manufacture this equipment, it is necessary to prepare a special rotor, which should be filled with an adsorbent made using a fiberglass carrier. In addition, silica gel and zeolite with activated aluminum oxide can serve as an adsorbent.

Cost and manufacturers of moisture absorber

When choosing a dehumidifier model, you need to pay attention to several main characteristics:

• Drying power;
• Operating temperature range;
• Tank capacity for storing water;
• Possibility to use continuous drainage;
• Automatic operating modes;
• Power consumption.

Nowadays you can buy both cheap and more expensive models. It all depends on the type of moisture absorber, its characteristics, as well as the manufacturer.

The leading manufacturer and developer of systems is the English company Calorex. It produces duct and monoblock devices.

Relatively cheap models are manufactured by a company such as EcoSystems. In addition, other concerns are also involved in production:

• Ballu,
• Aucma,
• Cooper&Hunter,
• Coughi, DTGroup,
• Dantherm,
• Ecor Pro,
• microwell,
• MyCond
• Neoclima by Hidros,
• Aerial.

A dehumidifier is a very important device that helps maintain the indoor environment at the proper level. Therefore, equipment should be selected carefully, carefully studying the quality characteristics.

A dehumidifier is a device designed to maintain a given level of humidity in a room, as well as get rid of excess humidity. A dehumidifier is indispensable if it is necessary to eliminate the consequences of high humidity - fungus, mold and prevent their occurrence. for an apartment, house, cellar, garage, pool you can at competitive prices.

How does a dehumidifier work?

Design and principle of operation of an air dryer

Most dehumidifiers operate on the principle of condensation of moisture in the air onto a cold surface.

The dehumidifier is equipped with two heat exchangers located one behind the other and connected into a single circuit, which is filled with refrigerant (freon). Using a compressor, the refrigerant is circulated in the circuit and maintained operating pressure. The fan forces air from the room through the dehumidifier.

Passing under pressure through a thin and long capillary tube, the refrigerant is greatly cooled, enters the first heat exchanger and cools it. Humid air from the room passes through the first heat exchanger, cooling and forming condensate, which flows into a special tray, and can then either be collected in a special built-in container or discharged into the sewer system through a drainage pipe.

The refrigerant from the first heat exchanger heats up, evaporates and enters the compressor. Due to compression, the refrigerant becomes very hot and enters the second heat exchanger. In it, the refrigerant condenses under the influence of passing cold air. At the same time, the air heats up.

Thus, the dehumidifier first cools, then condenses moisture and heats the air.

What types of dehumidifiers are there?

Depending on the purpose, there are Various types dehumidifiers.

How to choose a dehumidifier?

To approximate the required drying regime and preliminary selection of dryers, it is enough to use empirical formulas, taking into account compliance with two basic requirements:

1. Dehumidification is carried out in indoors.
2. The room temperature is within the operating temperature range of this dehumidifier.

APPROXIMATE CALCULATION OF THE REQUIRED DRYING MODE.

Designations:

Q - required moisture removal, l/h

V - room volume, m3

Vdr - volume of drained wood, m3

Rdr - density of dried wood, kg/m3

S - pool mirror area, m2

A detailed description of the dehumidification system design methodology is given in the Dantherm Dehumidification System Design Guide - 1998.

Application area	Required moisture removal, l/h	Conditions
Dry storage(warehouses)	Q = Vx 1.2 x 10-3	Air exchange rate 0.3 Drying rate 2.5 g/m3 h Air temperature 20 °C
Dehumidification of residential and administrative premises	Q = V x 1.5 x 10 -3	Air exchange rate 0.5 dehumidification 2.5 g/m3 h Air temperature 20 °C
Drying buildings	Q = V x 2.0 x 10-3	Air exchange rate 0.3 Drying rate (taking into account the evaporation of moisture from wet materials) 3.2 g/m3 h Air temperature 20 °C Drying period 8 days
Drying wood	Q = Vdr X Rdr X 0.4 X 10 -3	Sealed drying chamber Air temperature 25-30 °C Relative air humidity 30-40% Drying rate 1% of wood moisture content per day
Swimming pool drainage	Private swimming pools up to 50 m2 (with protective cover, limited load): Q = S x 0.1 Public swimming pools over 50 m2 (without protective coating, at normal load): Q = S x 0.2	Inflow of outside air - (10 x S) m3/hour Air temperature - (t water + 2) °C Relative humidity - 60%

VDI 2089 STANDARD FORMULA

The evaporation rate is calculated as follows:

W = e x S x (Pnas - Rust) g/h;

Where:
S is the area of ​​the water surface of the pool, m2;
Pnas is the water vapor pressure of saturated air at the water temperature in the pool, mbar;
Rust - partial pressure of water vapor at a given temperature and humidity, mbar;

E - empirical coefficient, g/(m2 x hour x mbar):

0.5 - closed pool surface,
5 - fixed surface of the pool,
15 - small private pools with a limited number of swimmers,
20 - public pools with normal swimmer activity,
28 - swimming pools for recreation and entertainment,
35 - pools with water slides and significant wave formation.

Example. Private pool.

Pool mirror 20 x 5 m S= 100 m2
Water temperature 28 °C (100% r.h.) Рsat = 37.78 mbar
Air temperature 30 °C (60% r.h.) Rst = 25.45 mbar

Evaporation rate
W = 13 x 100 x (37.78-25.45) = 16029 g/h = 16 l/h Rust - water vapor pressure of saturated air at a given temperature and air humidity, mbar

a is the coefficient of pool occupancy by people:

1.5 - for play pools with active wave generation,
0.5 - for large public swimming pools,
0.4 - for hotel pools,
0.3 - for small private pools

Many people face the problem of dampness in own homes and even in apartments. Humidity itself may not become a critical threat, but the possibility of the development of pathogenic flora, mold formation and the general atmosphere of such damp housing are not at all encouraging. Sometimes it happens that dampness has a local distribution - for example, a bathroom or kitchen. In any case, a solution to this problem has been found. If you want to get rid of dampness in your home, then you need to use household dehumidifier household level.

All dehumidifiers can be divided into domestic and industrial. Household dehumidifiers used in apartments, houses, cottages and country houses.

Let's stop and look at a household air freeze dryer. The design, dimensions and operating principle of this dehumidifier can be very different. The air dryer can be mobile, wall-mounted or floor-mounted. To remove moisture, air cooling, hygroscopic material, heating, or other equally intriguing sublimation methods can be used. The question is what effect you want, and what humidity a particular device will have to deal with. The main thing to remember is that you can buy a freeze dryer at any time.

The choice of design should be made based on practical conditions. If you have a generally high level of humidity in your apartment, then ideal option is household dehumidifier. If moisture is spreading from a specific room, or even a corner, then it is wiser to install the device there in order to stop the spread of the problem in principle.

Lyophilizers (air dehumidifiers) will help maintain the required level of humidity in your home. Thanks to this modest device, the microclimate of your home will become healthier and more pleasant.

Buy household dehumidifiers You can visit the online store website. To do this, you need to place an order through the website or contact the manager by phone.

Air dehumidifiers, like other climate control devices, are designed to maintain a microclimate that is favorable for living indoors. It is advisable to use them in rooms with high humidity and insufficient ventilation. Using a household dehumidifier eliminates the possibility of mold and mildew and the rapid transmission of viral diseases between family members. The use of these devices is especially important in the off-season, when central heating turned off, and the humidity in apartments is especially high. If you care about the microclimate in your home, we suggest that you familiarize yourself with the rating of the best dehumidifiers.

To create indoors comfortable conditions for life, today there are many climate control devices. One of them is a dehumidifier, which is an industrial and household moisture absorber. In fact, this is monoblock air conditioner. It is widely used not only in apartments or private houses, but also in swimming pools, production premises.

What is a dehumidifier

A home dehumidifier is a device whose function is to reduce air humidity. The main characteristic of the device is performance, which determines how much water the device can remove per unit time at a certain humidity and air temperature. This parameter is measured in liters per day, and for household and semi-industrial modifications it is equal to 12-300 l/day. Another characteristic is the noise level, which is very important for domestic wet rooms.

Working principle of a dehumidifier

Before you buy an inexpensive dehumidifier for your apartment, find out how it works. The operating principle of this household appliances based on moisture condensation when air masses come into contact with a cold surface. Using a fan, air is supplied from the room to the evaporator, which is a radiator with low temperature. Next, the air cools, and the moisture from it condenses and flows into the pan. After this, the air mass is supplied to the radiator with elevated temperature, where it is heated and fed back into the room.

Adsorption type

The operating principle described above is common to most modern air dryers, but if we consider it in more detail, it may differ slightly depending on the modification. The operating principle of an adsorption dehumidifier is based on the adsorption of water vapor contained in the air. Subsequently, the adsorbent must be replaced or regenerated, i.e. dried. The air into the device passes through the main part of the rotor (silica gel), as a result of which moisture is absorbed by the silica gel.

Condensing type

The operating principle of industrial and household condensation-type air flow dehumidifiers is based on the condensation of moisture (water vapor) on the surfaces of the evaporator, which has low temperature. In essence, such a device is an air conditioner that simply does not have the function of removing heat from the room. The water vapor condensed on the surface of the evaporator is subsequently removed. Any such moisture collector works with air superheating, from which sensible and latent heat is removed.
